Tentukan nilai x yang memenuhi setiap persamaan berikut 1. -5 (3x - 7) + 4 = 14 2. (X + 5)=6 3.2 (-2x - 2) -3 = 13 4. (2x -1)=(x + 3) TOLONG DIJAWAB YAH

1)
-5(3x-7)+4 = 14
-15x+35+4 = 14
-15x+39 = 14
-15x = 14-39
-15x = -25
x = -25/-15
x = 5/3

2)
(x+5) = 6
x = 6-5
x = 1

3)
2(-2x-2)-3 = 13
-4x-4-3 = 13
-4x-7 = 13
-4x = 13+7
-4x = 20
x = 20/-4
x = -5

4)
(2x-1) = (x+3)
2x-x = 3+1
x = 4
